Specification forming part of Letters Patent No. 85,493, dated December29, 1868.

'To all whom it may concern:

Be itvknown that I, STEPHEN D. TUCKER, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Machinesfor Printing and Numbering Railway Coupon-Tickets and similar articles;and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and the gures and letters of reference thereon.

Figure 1 is a perspective view of the machine 5 Fig. 2, a side elevationwith a portion of the frame broken away to exhibit more plainly theinterior parts. Fig. 3 is a rear view of the upper portion of themachine; and Figs. 4 and 5 are views of the mechanism controlling thereverse motions of the impression-cylinder.

Similarletters of referenceindicate like parts in the several drawings.

My invention consists, first, in an arrangement and combination ofmechanism for operating the type-bed; second, in the construction andarrangement of the impression-cylinder; third, in the combination andarrangement of mechanism for entering and delivering the sheets; fourth,in the combination 'of the sheet-flier with a reciprocating rotatingimpression-cylinder fifth, in the combination of vthe puncturing-rollerswith a'reciprocatin g rotating impression-cylinder, sixth, in theemployment of cords for conducting the sheets to and holding them on theimpression-cylinder and taking them from'the type; seventh, in thecombination, with a reciprocating rotating impression-cylinder andtype-bed, of the numbering-wheels; eighth, in the combina` tion, withthe numbering-wheels, of the inclined planes for operating them; ninth,in operating the numbering mechanism through the medium of thereciprocating type-bed and the inclined planes tenth, in thecombination, with the numbering-wheels, of the springs for forcing thepawls into their respective notches, s0 as always to insure properrotation of the wheels, in combination with a reciprocating type-bed.

kTo enable others skilled' in the art to make VY`and use my invention, Iwill describe its construction and operation.

.The several parts constituting the frame of the machine consist of thebase B, side frames A A, and end bars C C. These, rmly united together,form the supports and bearings for the various mechanisms.

To the end bars C 0 are secured at each end two bars, D D, grooved toreceive the guidepieces F F, secured to the under side of the type-bedE.

The reciprocating movement of the typebed E is effected by means of therocking levers H H, having bearings in the lower part of the sideframes, the arms I I of these levers connected with the bed by the rodsJ J pivoted to them and to the under side of the bed at K, and the gearM and wrist-pin N, working in the slot in the yoke L, which is pivotedto the levers H H.

The driving-shaft S is provided with bearings in the side frames A. Onits ends is secured the pinion T, which meshes with the gear U and theiiy-wheel R. or pulley, by which motion is imparted to the machine. Onthis shaft, nearits center, is secured a pinion, O, which transmitsmotion to the gear M. The shaft of this gear has [its bearings in thehanger X', bolted to the under side of the left guidebar D, and in thecenter standard of the side frame. This shaft also gives motion to thecam Q that is secured to its outer end. The form of this cam Q isrepresented in Fig.

4. Its ofice is to operate and control the lever Y pivoted to the sideframe A.

The gear U is constructed with cam-grooves U U on both faces, in whichthe rollers of the forked arms V W work. Through their medium motion istransmitted from the driving-shaft tov the shafts J K', which operaterespectively the feeding-table and sheet-nier.

'lhe rack G, secured to the side of the bed E, communicates motion tothe segment-gear B' on the right-hand end of the impressioncylinder, andalso, by means of said cylinder, operates the puncturing-wheels c c cthrough the agency of the gear on the other end of the cylinder and thepinion C' on the shaft D.

The puncturing-wheels are held in place on the shaft Dl by set-screws,and are arranged to be adj usted at any required distance apart in orderto agree with the diiferent divisions of the ticket to be printed,between which the punctures are to be made.

The bearings d of the shaft Dl are pivoted to the inner side of theframes, and are provided with adj ustin g-screws c o, by which thepunctnring-wheels can be adjusted at any required distance from theimpression-cylinder. The ends of these screws are held against the partof the side frames immediately beneath them by the springs which aresecured to the inner side of each frame, and press against the upperpart of the bearings, as shown in Fig. l.

On the longer end of the cylinder-journal is secured a wheel, X,provided with two teeth, Z l, which vengage with the forked end m of thelever Y. By these parts the reverse motions of the impression-cylinderare controlled, and the cylinder made to change its position in relationto the bed E once for each entire movement of the bed, either backwardor forward.

The teeth on the gear B', which engages with the rack G, are cut away ona portion of the circumference to permit the rack, at the properintervals, to slide beneath the gear without giving motion to it.

The numbering mechanism O' is constructed of a series of wheels, withthe numerals on their face, and operated by the pawls t' i, the same asis now in general use in numberingmachines. This mechanism is secured toa late, N', attached to the rear end of the type- Although but oneseries of numberingwheels is shown in the drawings as attached to themachine, it is necessary, for the proper workin g of the machine, thatthere should be as many series of wheels secured to the plate N' asthere are coupons or tickets to be numbered.

The plate N' is designed to be detachable from the machine, tofacilitate the operation of changing the mechanism for different sizesof coupons or tickets to be numbered, several plates being arranged,with different numbers of series of wheels secured to each., so that oneplate can be removed and another attached in its place with facility.

The numberngwheels are operated by the rod P', that is held in slottedbearin gs T' T' on the sides of the type-bed. The ends of this rod areprovided with rollers S' S', which work on the inclined planes R Rsecured to the inside of the frames A.

At each backward movement of the typebed the numbering-wheels arerotated immediately after the impression has been given, and before theyreach the inking-roller F', by the action of the inclined planes R' R',which raise the rod 1)', on which the ends of the pawls t' i t' rest.

On the end bar C, at the rear of the inaehine, is secured a plate, Q',holding a series of springs, h h h. They are placed in line with thenumbering-wheels, and are employed to insure the pawls being forced intotheir respective notches in the wheels.

`On the shaft E', that is held in bearings on the top of the frame, isarranged a series of cord-pulleys, G' G' G', to which one end of each ofthe cords l b I) is secured, while the other ends are attached toadjustable eyes sliding in a groove in the impression-cylinder, and heldin place by clamping-screws. These cords are kept taut by the weight Zattached to the end of the band I'. They perform the oiices ofconducting in the sheet to receive the impression, holding it securelyin place on the cylinder, and drawing it oft' the form and delivering itto the sheet-Hier.

The feeding-table is provided with a gageplate, K, adjusted by means oftwo set-screws, and it is so moved by the shaft J that it an proachesthe cylinder at the proper time to introduce the sheet to the cords, andthen recedes to allow the sheet-flier to receive the sheet from thecylinder.

By the employment of the mechanism above described, that imparts motionto the impression-cylinder, the cylinder is caused to change itsposition with reference to the type-bed, so that the sheet on thecylinder to be printed shall be brought in contact with the form of typewhen the cylinder and bed are movin g in one direction, but shall escapethe form and receive the impression from the numbering wheels whenmoving in the opposite direction.

The inking apparatus for inking the form and numbering-wheels beingsimilar to the devices in general use in printing-machines, noexplanation of the same is necessary.

The operations ofthe different mechanisms constituting the machine willbe as follows: On motion being given to the fly-wheel It in thedirection of the 'arrow shown in Fig. 2 of the drawings, the pinion onthe center of the drivin g-shaft will operate the gear M, and a forwardmovement of the bed upon which the form of type has been previously laidwill take place. At the same time, the rack G of the type-bed, engagingwith the segment gear of the impression-cylinder, will communicate arotary movement to it. When the cylinder has arrived at its properposition to receive the sheet the feeding-table L', upon which the sheetis laid, is moved forward in the arc of a circle through the medium ofthe pinion on the end of the driving-shaft, and the gear engaging withit that operates the cams U' U' and their followers, and the sheet isintroduced to the cylinder, being caught and held against it by thecords. As the motions of the type-bed and cylinder are continued, theform of type is carried from under the inking apparatus F' and broughtin contact with the sheet on the cylinder, to which the impression isthen given. By the use of the segment gear on the impression-cylinderthe rack then becomes disengaged from it, and the type-bed is drawn backfor a short distance, while the cylinder remains stationary. As the rackis disengagedfrom the segment-gear one of the teeth of the wheel X iscaught by the end m of the lever Y, and the cylinder is then held atrest until the bed moves back far enough to prevent the form from againcoming in contact ywith the preach the inking apparatus, the inclinedform of type while the cylinder and bed are sheet when the motion of thecylinder is reversed, and also to bring the numbering mechanismatt-ached to the type-bed in proper position to imprint the numbers inthe spaces left on the sheet to receive them. The cam Q then causes thelever Y to turn the cylinder back sufficiently to cause the segment gearto again engage with the rack, and the impression-cylinder is revolvedin the opposite direction by the continued back motion of the type-bed.The numbers are then impressed on the sheet. The sheet is then carriedby the further motion of the cylinder into position to be received bythe sheet-Hier. Immediately after the impression from the numbers hasbeen given, and before they applanes R Rzact upon the rod P', and causeit to operate the pawls of the numbering-wheels.

As the type-bedceases' its backward motion, preparatory to being againmoved forward, the lever y repeats its moyements,'to hold the cylinderat rest and throw the segment-gear in contact with the rack, so that thetype-bed resumes its former position in relation to theimpression-cylinder before the form of type is brought in contact withthe sheet.

The feeding-table is so operated that a second sheet is fed into thecylinder as it commences to revolve toward the form of type, andimmediately after the first sheet has been taken by the sheet-nier.Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-H l. The wrist-pin N, slotted yoke L,rocking levers H H, arms I I, and rods J J, for operating the type-bed,substantially as described and specified.

2. Giving the impression-cylinder a reciprocatin g rotating movement, ineo-operative relation with the type-bed, so that the sheet to be printedshall come in contact with the traveling in one direction, and escapethe form and come in contact with the numberingwheels when traveling inthe reverse direction, substantially as described and specified.

3. The feeding-table, so constructed and operated that it shall approachto enter the sheet between the cords and the cylinder and recede toallow the sheet to be delivered to the sheet-flier, in combination witha reciprocating rotating cylinder and type-bed, substantially asdescribed and specified.

4. The' combination of the sheet-Hier, constructed and operatedsubstantially as described, with a reciprocating rotatingimpression-cylinder, as described and specified.

5. The combination ofthe puncturing-rollers c c with a reciprocatingrotating impressioncylinder, substantially as described and specilied.

6. The arrangement of cords b b b, pulleys Gr G G, and weight Z, forconducting the sheets to and holding them against the cylinder andtaking them from the form of type, substantially as described andspecified.

7. The combination, with a reciprocating rotating impression-cylinderand reciprocating type-bed, of the numbering-wheels, substantially asdescribed and specified.

8. The combination, with the numberingwheels, of the rod P' and inclinedplanes It' R', substantially as described and specied.
